Can someone help me with reverting to stock rom. Last week I tried some custom roms from XDA in my OnePlus 6t. As I am new to this A/B partition thing it took me so much time to finally install roms. Now I wants to revert to my stock rom.
I tried installing rom through fastboot 10.3.1 so that I could install the latest full ota file manualy from local storage.
I successfully installed stock rom through fastboot, but everytime I update to latest rom after completing to 99% I get error "System update installation failed". I tried installing fastboot rom manually, through MSM tool but nothing solved the problem.
Can someone help me to know what might be causing this problem

A question, so my phone is a Tmobile varient and because of a prior qualkum crash dumb I saw my self having to flash the T-Mobile OnePlus 6T Internationa ROM to bring it back to life. At first there was no magisk (which is what I want, dont want root only unlocked bootloader) but when I updated to the latest version (trough system updater) I noticed that there was now root. wast there always root and I just never saw it? how to uninstall? my plan is to unlock bootloader and get rid of tmobile stuff, will this affect me in any way? thanks.

Could you please add 10.3.4?

Thanks

With open bootloader can fastboot rom be used to downgrade from 10.3.4 to any version like 10.3.2 or pie.

Hi there,
today I got my new op6t with the Oxy version 9.0 and wanted to install the current LionageOS 17.1 immediately.
I got the PlatformTools_30.0.3 for Linux and unlocked it successfully according to the following instructions (https://www.cyanogenmods.org/forums/topic/unlock-bootloader-android-phone-using-fastboot/).
Afterwards I wanted to flash TWRP according to these instructions (https://www.cyanogenmods.org/forums/topic/install-twrp-recovery-android-using-fastboot/), which was also successfully completed.
But after a reboot nothing worked and my op6t stuck in the unlocked screen. The first rescue attempts I made with the following instructions from here (https://forum.xda-developers.com/oneplus-6t/help/urgent-recovery-os-stuck-bootloader-t3995935), whereupon I first flash the A side, then also the B side.
...unfortunately without success, the error was the same and I stuck on the unlocked screen.
Then I found this article and I followed the instructions:
MANUAL FLASH: Windows - OSX - Linux --> Fastboot Partitions
Unfortunately the script remains stuck at the following position:

./fastboot flash vendor_a vendor.img
Invalid sparse file format at header magic
Sending sparse 'vendor_a' 1/2 (511139 KB) _

the same happens when i want to flash the following image
vendor_b vendor.img

At the moment the device is useless and stuck on screen "Your device is corrupt..."
The only thing I can do is to send it to the fastboot and the original recovery mode.
_______________________________
I could solve the problem myself.
I installed TWRP again and then had the possibility to install the current original OOS with everything that goes with it.
I was lucky

Anyone successfully used the 10.3.5 fastboot rom yet? 10.3.4 works for me, but 10.3.5 won't boot. In fact it requires me to use the MSMTool to get my phone to work again after using it. The SHA1 hash matches the SourceForge one, so supposedly my download should be good?

Can't I use twrp to flash the stock rom to both slots the type fastboot OEM lock then reboot device and be good to go?

Can I lock the bootloader after flashing this ROM?

Can I lock the bootloader after flashing this ROM hoping it won't brick the phone?

Hi. I have tried flashing persist.img which I thought will fix my fingerprint sensor, however it did not. Anyone know how to fix fingerprint not working? It's a new fingerprint scanner which has just been replaced so I didn't think the fingerprint is faulty.

I wouldn't ever lock a bootloader. Why? I've read about a few users getting stuck on crashdump and they have locked bootloader's and oem unlocking not enabled and no way to access their screen to enable it to fix their device. I would leave it unlocked if I were you.

In the instructions for manual flashing, it says: "If you need also persist partition, this is the command:"

What's a "persist partition", and how do I know if I need it?

I'm currently stuck in Fastboot Mode on my phone. These instructions seem pretty straightforward, but I'm wondering if I could make a mistake and leave my phone in an even worse state than it is now. Could I possibly overwrite and mess up Fastboot?

My 6t was stuck in fastboot a few days ago. Thankfully, I ran the batch file just like the OP instructed. It took a while, but I left my phone alone. Once the process completed, my phone was restored in a factory reset state. The batch file is much safer than manual flash (in my opinion).

Could you add the 10.3.7 release please?

You can make your own fastboot ROMs easily too from the 10.3.7 zip if you need it now.

See this post

Does anybody knows why I am getting this error on Fastboot ROM 10.3.3? I am on A11 cutom ROM. Thanks.
